Introduction of coupling
Coupling is used to link the two different organization shafts (positive shaft and driven shaft) together with the
transfer of the rotating torque of mechanical parts. In the overloaded power transmission, some coupling can
improve the vibration and reduce shaft system dynamic performance of the role. It consist of 2 parts, positive
shaft and driven shafts . Generally speaking, power run by coupling and most work be connected to the machine.
Advantages
1.great variety of goods2.cushion and vibration, can compensate for the larger axial displacement3.high quality,good price
4.short delievery

Size, installation and maintenance
Must be in the installation of equipment allowed within the space. Convenient installation to choose between maintenance, the maintenance period, and not long or easy maintenance, replacement without moving parts, two axis, on the adjustment easily couplings. Big machine equipment adjust two axis is difficult to, should choose to use durable and replacement parts, convenient couplings. The flexible coupling metal components elastic usually better than the flexible coupling nonmetal elastic elements with long service life. Need to seal lubricants and use not durable coupling, will surely increase of maintenance. For long-term continuous operation and economic benefit of higher situations, such as metallurgical enterprises in our country of rolling mill drive system GaoZengDuan, widely adopted now is an coupling, gear couplings although theoretically transfer torque is big, but must be in good lubrication and seal under the conditions of the work can be durable, and be always check seal condition, note lubricating oil, maintenance workload big, increased the auxiliary hours, reduce the effective work time, influence the production efficiency.
How to choose coupling
Coupling varieties, type, specification many, in the correct understanding varieties, type, specification based on the concept of their respective, according to drive system need to choose the coupling, first from has formulated for the standard of the coupling choice, at present our country make for gb and line mark there are more than ten, these standards coupling most is the universal shaft coupling, each kind of coupling all have their own characteristics and applicable range, can meet the various modes of the basic needs, usually design personnel does not need its own design coupling, only in the existing standard coupling can not meet the requirements should be when designed by coupling. Standard coupling of choose and buy, the convenient, price to design non-standard couplings are much cheaper. In many of the standard coupling, the right to choose to suit oneself the best coupling, related to the shaft transmission of mechanical products work performance, reliability, service life, vibration and noise, energy saving, transmission efficiency and transmission precision and economy, a series of problems, but also related to the mechanical product quality.
